What is the smallest bird in the world? You wouldn't have guessed!
The smallest birds in the world are a class of birds called hummingbirds. Hummingbirds are usually very small, only 5-9 cm long and weigh only about 2-6 grams, which is equivalent to the weight of a credit card or a coin.
The smallest of these hummingbirds is the Mellisuga helenae, also known as the Schwartz hummingbird. With a body length of only 5.5 centimeters and a weight of only 2.5 grams, they are one of the smallest known birds. They are found mainly in the Isla Draz and Santa Clara regions of Cuba and live in forest and grassland areas.
Although the Goo's hummingbirds are small, they have a very strong ability to fly. They can vibrate their wings at a rate of 80 times per second, up to more than 4800 times per minute, which is the fastest wing vibration rate of any bird. The Gu hummingbird is also the only hummingbird that can feed upside down on plants, due to the special adaptations of the shape and length of their mouths.
In addition to hummingbirds, there are some very small birds, such as another bird called the Pacific Canary, which weighs only about 2 grams and is one of the lightest birds currently known. The world's smallest eggs are laid by another hummingbird, the bee-tailed bird, whose eggs are only about 1 cm long and weigh about 0.357 grams.
In addition, hummingbirds are also very sensitive animals, they fly very fast, some hummingbirds can hover in the air, flying speed can reach more than 100 kilometers per hour. At the same time, hummingbirds are also very intelligent animals, they are able to remember every flower they have visited and know which flowers have the sweetest nectar.
